A Synthetical Evaluation Method of Torpedo Maintainability Based on VR

As an important product characteristic, maintainability is recognized as a highly significant factor in the economic success of engineering systems and products. With the rapid development of Virtual Reality (VR) technology, an intuitive, immersive and interactive environment for product maintenance is created in this paper. In order to analyze and evaluate the product maintainability in virtual maintenance environment, fuzzy comprehensive evaluation is used. At stage of early design, maintainability influencing factors are analyzed and the whole maintainability evaluation of product is given by using fuzzy comprehensive evaluation method in virtual maintenance environment. Then a torpedo is as a case to be studied in this paper.
